My goodness, what a slender waist! And your face is so small — you look like a little doll!
Literal
My-my [what-a-なんて] slender waist [copula-な] [emph-の]! Honorable-face [also-も] is-small-[and-て], really honorable-doll-[polite-さん] [like-みたい]!
なんて + [adjectival phrase] is the exclamatory 'what a (adjective)!' pattern. なの is the feminine copula-の ending, soft and emotive. The honorific prefix お on 顔 ('お顔') adds gentle politeness typical of feminine speech; 人形さん 'Miss doll' similarly uses the affectionate suffix さん on an inanimate noun to sound endearing. みたい is the colloquial simile marker 'like / as if.' The whole line is saturated with feminine speech markers — a useful calibration point for spotting the register at a glance.
